I've rebuilt cleanly using 2.4.19-2 today. Unfortunately, even though
it worked without trouble in the older version, it now gets this:
sleeping process 2449 got unexpected signal : 11
and then it dies. this happens after system startup, right at the login
prompt:
Unauthorized access to this system is strictly prohibited.
redhat62 login: sleeping process 2449 got unexpected signal : 11
any ideas? what should I do to help pinpoint the problem?

Thanks, but I'm fairly (not entirely, but fairly) sure that this is not
the problem. Not only because the machine has been running just fine
for over a year, but also because the older uml patch worked fine, too.
Only the new one creates this bug *and* it creates it very, very
reliably. In fact, I can reproduce this at will. Doesn't sound like
flaky hardware to me.
Plus, it didn't crash a the kernel compile. It compiled it just fine
(several times even). This message comes when I try to *run* the uml.

You may very well be correct - it may be a uml kernel bug of some
sort.
When you compiled the UML kernel did you use the default 386 CPU
settings?

uh, the CPU settings vanish if ARCH=um is set. or are you talking about
something else?

For this one, you basically don't have to do anything. Just make it happen,
and tell me how to get to it.

well, it actually is very simple:
./linux honeypot fake_ide fakehd mem=128M eth0=tuntap,tap0 devfs=mount
This error appears after boot, at the moment the login prompt appears,
before I've typed anything.
Unfortunately, reproducing is somewhat tedious, since it involves a fs
check. However, It isn't a general failure. starting just
./linux
works fine. However,
./linux honeypot
results in the mentioned crash. at that point, it doesn't seem to take
any keyboard input on the console anymore, so I've gotta kill it.
is that of any help?
